ROLLER SIDE BEARING.

Specicathn of Letters Patent.

Application inea June s, 1917. serial No. 173,848.

lo all whom it may concern lie it known that4 1. Joux lf. OCoNNon, a citizen of the United States. residing at Chicago. in the tounty ot' Cool: and State ot' Illinois, have invented a certain new and useful Improvement in Roller Side Bearings, of which the following is a full. clear, concise, and exact description. reference beina,r had to the accompanying drawings, forming. a part of this specification.

This invention relates to improvements in roller side bearings.

The object ot the invention is to provide a simple and relatively inexpensive roller side bearing wherein are employed gravitycontrolled members separate from the roller for returning the roller to normal position after each actuation.

In the drawing forming a part of this specification1 Figure l is a longitudinal vertical sectional view of a roller side hearing showing one embodiment ot' the invention. Fig. 2 is a transverse vertical .sectional view, taken on the line 2--2 of Fig. l. And Fig. 3 is a view similar to Fig. l. hat illustrating another embodiment ot' the invention.

In said drawing. 1() denotes a portion of a truck bolster to which the improved roller side bearing A is ln'et'erahly attached, and 11 the under side of a body bolster.

The roller side bearing A, as shown, coinprises a base riveted or otherwise seem-ed to the bolster l0, opstanding side walls 13-1}, upwardly and outwardly inclined end wallsl ll--14, an insert tread-plate l5, and oppositely arranged, duplicate sets of inclined guidingledges or run-ways 16 and 17 on the inner face of each side wall 13. The anti-frict'on roller 18 normally occupies the position shown in Fig. l and to maintain the latter in central or normal position, the followingr gravitycont rolled means are employed. 0n each side of the roller` 18 is a transversely extending' -rod `or roller 19 which extends from side to side of the casting and is supported and guided by the run-ways 16 and 17. Due to the o posite inclination of the run-ways 16 and 1g, it is apparent that each rod or roller 19 will normally occupy the lowermost. position thereon, as indicatedjn Fig. 1 by the full lines. The rollers or rods 19 are each journaled at their ends in connecting links 20-20 at, each end of the roller;n said links 20 being upwardly in- .rlm-Ways 1G and 17.

castingr havinglr a lower wall 12 placement or removal ol1 clined, as clearly illustrated in the dra wing.

to thereby clear the hig'h portions ot' 1he liy connecting the rollers ltltogether, it is apparent that Ille same will move in unison and thereby employ tlie Weight 0f liotll ol` said roller to return the anti-friction roller lH to normal position after each actuation ol' the latter. In Fig. 1, the dotted lineay ind de the extreme position of the parts when the antifriction roller 18 has been moved to one aide and duringr this movement. il is apparent; that the roller 18 will torce the lel'l hand rod 19 up the incline lli and drag the other roller 19 up the correspomliimr parallel runway 1G. The roller 18 is limited in its move ments by stop shoulders 21-21 and aimilal'ly the rods 19 are limited in their upward movements by curved recesses 22h22 on the inner faces of the end walls 1l of the hase casting. After the anti-friction roller 1S has been moved to the position indicated hv dotted lilies in Fig. l. and lhe pressure from the body bolster removed. it is olivione that lioh the rollers or rods ll.l will gravilate down'the run-way.` lfi and thereby pull the roller 18 back to central position.

The roller 18 is centrally rei-eend, as inY dieated at 122 and a loose rod 23 mayhe extended thcrethrong'h. which rod is adapted to freely slide bach and forth in longitudinal slots 2l inlhcside walls lil. the rod 23 being adapted to prevent accidental dislhe roller lh'.

In the construction illustrated in Fig. 3. the arrangement ot' hase casting, antifriction roller. side walls of the hase casting, end walls` of `the. base casting. and guideledgcs orlrunI-ways. is the same as in the structure illustrated in Figs. 1 and 2. In the arrangement shown in Fig. 3, however. the. gravity rods or rollers 119 arf` inde pendent ot' each other so that, as the antifriction roller 118 moves to either side' oii normal, only one of the gravity rollers 11S) will be forced up a run-way and conscquently, there will be only one of said gravity rods or rollers` to force the anti-friction roller 118 hack to normal position.

1 claim:

1. In a roller side bearing, the combination lwith a base member having a bearing;r surface `for an anti-friction roller, of an antifriction roller, inclined guide-ways, and a gravityv rod freely mounted on said guide-ways and adapted to tan renti-ally enruge .Suid roller, the rod normal y resting in its lowerlnost position on the guide-ways and adapted to be displaeeable upwardly thereon when the anti-friction roller is moved froin nornml position, whereby said gravity rod is adapted to return the antir'ction roller to normal osition.

2. In u roller Side bezlrlng, the combinaition' with un anti-friction roller, of a housing,r within which said roller is mounted and freely 1i'io\':1ble,'suid housing having sets of inclined guide-ways on both sides of the roller, and ravity rollers on each side of the anti-friction roller riding 0n said inclined guide-ways and adapted to return the anti-friction roller to norma] after each actuation, under the influence of gravity.

3. In a roller side bearing, the combinetion with a base Casting having parallel side walls and end walls, of an anti-friction roller mounted within said hase eating,

two sels of inclined guide-ways on the inner side of ene-l1 of Suid Side walls, and lrunsversely extending gravity rods supported :it their ends on said gnide-wavys, said gravity rods being dispdsed on opposite sides of the antrfrietion roller.

4.. In a roller side hearing, the Combination with u base casting having parallel side walls and end walls, of an nnti-frie tion roller mounted w'ifhin said buse casting, two sets of oppohilely inclined guideways on the inner :side of each of Said side Walls, and transversely extending gravity rods supported at their ends on said guideways, said gravity rods bein disposeo on opposite sides of the anti-ietion roller, und means for moving said gravity rods in unison. y

In witness that I claim the foregoing I have hereunto subscribed by name this th day of May, 1917.

JOHN F. OCONNOR.
